I am attempting to save my friends computer. It is really important the person I am doing it for did somethaing for my father who is dying of cancer and I have to fix it. It is a Toshiba satellite A305-S6916. I saved his data and bought a new hard drive, his was gone. I installed it and put in my windows 7 recovery disk and it starts to load and then goes to a black screen. In safe mode I get a blue screen. Is the second hard drive bad or do I need to load Toshiba drivers first. I have a dell inspirion and I am about to take it apart to try out the driver in my computer but I can't afford to make an error. Please help. Would purchasing the Toshiba recovery disk work?
